Abstract
The present invention discloses a planar carbon commutator for a motor, which comprises a commutator segment 1, a molding material 2 and a carbon block 5, wherein a body 6 of the commutator segment 1 is perpendicular to a line of a rotation axis of a commutator, the commutator segment 1 is arranged in the molding material 2 and is exposed out of the outer surface of the body 6 of the commutator segment, the outer surface of the body 6 of the commutator segment is plated with a silver-copper alloy layer 3 which is coated with a mixing strong adhesive layer 4, and the carbon block 5 is arranged on the mixing strong adhesive layer 4. The present invention solves the problem of complex structure existing in the prior planar carbon commutator and has the advantages of simple structure and convenient manufacture. Accordingly, the present invention saves the labor time, reduces the production cost, and completely accords with the requirements in the aspect of the service performances of a motor, such as spark, noise, service life, etc.
Description
One, technical field
The present invention relates to the commutator that a kind of motor is used, particularly relate to a kind of flat carbon commutator.
Two, background technology
Chinese invention patent specification CN 1046598C (Granted publication day: on November 17th, 1999, the patent No. 95102934.7) a kind of planar carbon commutator segment type commutator and manufacture method are disclosed, comprise basal component (can claim moulding compound), contact member (can claim commutator segment), carbon commutator segment (can claim the carbon piece), basal component has a plurality of first containing nests that stretch backward from its front end, and the carbon commutator segment is formed on the contact member and has and stretches into the described first integrally formed anchor that contains in the nest backward; This anchor has and engages with the rear surface of contact member to prevent that anchor from containing interlocking that nest throws off vertically partly from first; The front end of basal component has a plurality of first areas, also have a plurality of from the first area to front protrusion and be separately positioned on second area between all adjacent first areas, circumferentially extending.Also have, Chinese invention patent explanation CN1094265C (Granted publication day: on November 13rd, 2002, the patent No. 98809820.2) a kind of carbon commutator and manufacture method thereof are also disclosed, comprise conductor part (can claim commutator segment), carbon plate (can claim the carbon piece), insulator wheel hub (can claim moulding compound), carbon plate is formed by the carbon component of conduction, the insulator wheel hub arrange around carbon plate with between carbon plate and mechanically interlocking live carbon plate, conductor part has the conductor protuberance, this protuberance part at least is embedded in the carbon plate, thereby contacts and reduce resistance by increasing surface area between conductor part and its corresponding carbon plate.
But, the complex structure of above-mentioned carbon commutator and basal component thereof (or insulator wheel hub), contact member (or conductor part), carbon commutator segment (or carbon plate), and the manufacture craft process is comparatively loaded down with trivial details, time-consuming, cost consumption is bigger.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and provide a kind of make the carbon piece easily, be securely fixed in the flat carbon commutator simple in structure on the commutator segment.
Purpose of the present invention realizes by following technical solution: a kind of flat carbon commutator, comprise commutator segment, moulding compound, carbon piece, the body of commutator segment and the rotation of this commutator are perpendicular, described commutator segment is located in the moulding compound and exposes the outer surface of the body of commutator segment, on the outer surface of the body of commutator segment, be coated with the yellow gold layer, scribble on described yellow gold layer and mix the strong rubber adhesion coating, described carbon piece is located at and mixes on the strong rubber adhesion coating.
After adopting structure of the present invention, only need on this external surface of the commutator segment of routine, to plate the yellow gold layer successively and mix the strong rubber adhesion coating, then under certain temperature and pressure, the carbon piece is compressed on mixes on the strong rubber adhesion coating.Therefore, the present invention compared with prior art has advantage simple in structure, easy to make, thereby has saved working time, reduced production cost.
Four, description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and execution mode.
Fig. 1 is the structural representation of flat carbon commutator of the present invention.
Fig. 2 is the partial enlarged drawing (ratio is 4: 1) shown in the A among Fig. 1.
Five, embodiment
With reference to Fig. 1, Fig. 2 as can be known, flat carbon commutator of the present invention, comprise commutator segment 1, moulding compound 2, carbon piece 5, the body 6 of commutator segment 1 is perpendicular with the rotation (O axle) of this commutator, described commutator segment 1 is located in the moulding compound 2 and exposes the outer surface of the body 6 of commutator segment, on the outer surface of the body 6 of commutator segment, be coated with yellow gold layer 3 (its role is to increase the outer surface roughness of the body of commutator segment), scribble on described yellow gold layer 3 and mix strong rubber adhesion coating 4, described carbon piece 5 is located at and mixes on the strong rubber adhesion coating 4.Wherein, commutator segment 1 is the yellow gold material, and yellow gold layer 3 is by forming with the identical or akin yellow gold of the material of commutator segment 1, mixes strong rubber adhesion coating 4 and is formed by electric conductivity good mixing strong rubber stick.Described commutator segment 1 comprises body 6, foot 7, also can comprise from the outer surface of moulding compound 2 stretching out and outstanding hook portion 8.
The present invention only needs to plate the yellow gold layer successively and mix the strong rubber adhesion coating on this external surface of the commutator segment of common plane commutator, then under certain temperature and pressure effect, with carbon piece and the compression moulding of mixing strong rubber adhesion coating.The body of commutator segment just can conveniently link together with the carbon piece securely by yellow gold layer and mixing strong rubber adhesion coating, and does not need the structure of commutator segment, moulding compound, carbon piece is carried out complicated design and processing.This flat carbon commutator can meet the requirement of various serviceabilities aspects such as motor spark, noise, life-span fully.
